1
The force per unit charge felt by an object in an electric field
2
Force, F (N) / Charge, Q (C)
3
Coulomb Constant, k × Charge, Q (C) / Distance from Charge², r² (m²)
4
Radially away from positive charges and radially towards negative charges
5
A field with the same strength at any point inside it
6
From parallel charged plates, one negative and one positive, creating a potential difference across them
7
The different charges between both plates
8
Voltage Drop, V (V) / Distance between Plates, d (m)
9
Equally spaced, Straight, Parallel
10
Force, F (N) × Distance between Plates, d (m)

1 - We know that W is also equal to the Charge, Q, × Change in Voltage, ΔV, 2 - Therefore Fd = Q × ΔV, 3 - Rearrange to get F/Q = ΔV/d, 4 - As E = F/Q, E also = ΔV / d
